Online stibium analyzer and method for detecting concentration of stibium of different forms in water sample

Abstract

The invention provides an online stibium analyzer and a method for detecting the concentration of stibium of different forms in water samples, wherein the analyzer comprises a control device, a quantitative sampling device, a reaction device, a detecting device, a water sample storage device and a reagent storage device. The control device is used for controlling the quantitative sampling device to obtain the water samples and reagents from the water sample storage device and the reagent storage device respectively, and filling the water samples and the reagents into the reaction device; the control device is also used for controlling the detecting device to detect the absorbance of complex generated in the reaction device, and feeding detecting results back to an analytical processing module; and the analytical processing module is used for analyzing the absorbance to obtain the concentration of the stibium of different forms in the water samples. The online stibium analyzer can be used for directly and automatically analyzing free stibium, total stibium, +3-valence stibium and +5-valence stibium in the water samples, so that the water samples can be monitored on line. In addition, owing to an extraction function, the online stibium analyzer is capable of detecting low-concentration stibium.

Description

technical field [0001] The invention relates to the field of environmental monitoring equipment, in particular to an antimony online analyzer for online monitoring of the concentration of free antimony, total antimony, antimony (III) or antimony (V) in water quality. In addition, the invention also relates to a method for detecting the concentration of antimony in different forms in water samples. Background technique [0002] Antimony is a non-essential element for living organisms. Most of the simple substances and compounds of antimony are toxic, and the toxicity of trivalent antimony is ten times higher than that of pentavalent antimony. Antimony can irritate people's eyes, nose, throat and skin. Continuous exposure can damage the heart and liver function. Inhalation of high levels of antimony can lead to antimony poisoning. Symptoms include vomiting, headache, breathing difficulties, and severe cases may cause death. Some studies have shown that antimony has chronic t...
